The US Army Field Band puts on a great Holiday concert every year here in Baltimore – they are very talented and accomplished musicians and singers performing both traditional and contemporary arrangements of holiday music. It’s a free concert –open to the public- runs a little less than 2 hours - held at the Lyric in Baltimore every year. It really provides a jolt of patriotic holiday spirit and pride in the talent and abilities of the young men and women who are serving today.
